16. stick--alluding to Nu 17:2, the tribal rod. The union of the two rods was a prophecy in action of the brotherly union which is to reunite the ten tribes and Judah. As their severance under Jeroboam was fraught with the greatest evil to the covenant-people, so the first result of both being joined by the spirit of life to God is that they become joined to one another under the one covenant King, Messiah-David.
      Judah, and . . . children of Israel his companions--that is, Judah and, besides Benjamin and Levi, those who had joined themselves to him of Ephraim, Manasseh, Simeon, Asher, Zebulun, Issachar, as having the temple and lawful priesthood in his borders (2Ch 11:12, 13, 16; 15:9; 30:11, 18). The latter became identified with Judah after the carrying away of the ten tribes, and returned with Judah from Babylon, and so shall be associated with that tribe at the future restoration.
      For Joseph, the stick of Ephraim--Ephraim's posterity took the lead, not only of the other descendants of Joseph (compare Eze 37:19), but of the ten tribes of Israel. For four hundred years, during the period of the judges, with Manasseh and Benjamin, its dependent tribes, it had formerly taken the lead: Shiloh was its religious capital; Shechem, its civil capital. God had transferred the birthright from Reuben (for dishonoring his father's bed) to Joseph, whose representative, Ephraim, though the younger, was made (Ge 48:19; 1Ch 5:1). From its pre-eminence "Israel" is attached to it as "companions." The "all" in this case, not in that of Judah, which has only attached as "companions" "the children of Israel" (that is, some of them, namely, those who followed the fortunes of Judah), implies that the bulk of the ten tribes did not return at the restoration from Babylon, but are distinct from Judah, until the coming union with it at the restoration.
